OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 240,322, datedApril 19, 1881. Application filed January 21, 1881. (No model.)

To all whom it may concern:

Be it known that I, HUGH McCoNNELL, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Oil-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to oil-stoves; and it consists in certain features of construction and combinations of parts, as will hereinafter be described, and pointed out in the claims.

In the drawings, Figure 1 is a vertical sec tional view of a stove constructed according to my invention. Fig. 2 is a plan view of the top. Fig. 3 is a view, in perspective, of a detached portion of the top, showing the locking mechanism for retaining the bolt which.holds the parts of the-drum together. Fig. 4 is a detached view, in perspective, of the bolt, together with the mechanism for operating the same.

In the said drawings, A represents the principal reservoir, whose bottom and sides are constructed of cast metal and made preferably in a single piece. The topis made of sheet metal, properly united at its edges with the sides. It may be supported by one or more posts, A, to prevent its displacement.

To permit the ready removal of any oil that may be in the reservoir at any time, for the purpose of cleaning, I have added to the side an outlet-pipe, a.

B is the supplemental reservoir of an oilstove. The office of this reservoir is to contain the wicks and a sufficient amount of oil tofurnish them with immediate supply. The upper portion of this reservoir is made of malleable iron, and the covering of tin, and bottom and sides of sheet-brass, which latter can be struck up into any desired form. The top being covered with tin and the bottom made of sheet-brass the two can be readily soldered together. I also provide an opening, B, in

- the upper portion of this supplemental reservoir. The object of this opening is to permit ready access to the interior of the supplemental reservoir B. It often happens that in the careless use of stoves of this character the wicks will get below the wick-raisers. Through this opening they can be readily taken from the reservoir.

To avoid the use of points in the top of an oil-stove and to secure a fiat top, I construct the stove with two tops or covers. The first top, 0, is adapted to fit closely about the drum, andact as an upper support to the chimneys, as shown in Fig. 1. The second or supplemental top, D, is provided with three or more lugs, D ,-which are adapted to rest upon the top O. The object of these lugs is to raise the top D sufficiently above the top 0 to permit the ready passage of heat and products of combustion from the chimneys between the tops 0 and D. I prefer to construct this supplemental top D as light and open as possible, one object being to permit the heat from the stove to strike the cooking-utensil without being at all obstructed, and as the heatipasses out between the tops to come in contact with as much of the bottom of the cooking-utensil as possible. Another object is to make the stove as light as possible, and also to prevent wear upon the bottom of the cooking-utensil, which is occasioned by the points, which is an objectionable feature to the old construction. In Fig. 2 of the drawings I show such a construction, the large central openings, D when the top is in place, coming directly opposite the chimneys of the stove. I

The drum of my improved stove is held together by means of improved mechanism shown in Figs. 3 and 4. This mechanism consists of the bolt E, provided with a lug, E.

The supplemental top D is provided with an opening for the passage of the bolt and the lug, and also surrounding this opening is a corrugated cam, D, upon which the lug E will rest when turned up or tightened. This boltE is made round and adapted to turn throughout its length, whereby the parts of the stove may be secured together by turning the bolt, causing the lug E to engage with the face-ratchet D. I propose to form the section of this bolt that would rest between the tops '0 and D with an angular portion, upon which can rest any suitable mechanism for turning it. In the drawings I have shown a wrench provided with handles that can be easily manipulated through the supplemental top D.

What I claim isbottom plate, drum, upper plate, and support 1. In an oil-stove, the combination, with its for cooking-utensils, of the bolt E, provided drum, chimneys, and top, of a supplemental top with lug E, corrugated cam D, and suitable I 5 having a flat upper surface and a single bolt mechanism for turning said bolt, substantially for securing the parts in place, substantially as set forth. as set forth. v In testimony whereof I have signed my name 2.
